First light of the day tries to break through the clouds over Mt Ida and the Travellers Range. The prominent cliffs and columns of the central highlands are made of Jurassic dolerite. This shot was taken from the southern end of Lake St Clair which is Australia's deepest lake owing its depth of 160m (or 525 ft) to its glacial origin. Unlike mainland Australia it is believed that Tasmania experienced four phases of major glaciation with a single ice cap covering about 4,000 sq km of the northwestern part of the central plateau along with other smaller isolated ice caps and valley glaciers. During these glacial periods sea levels were low enough to open the Bassian landbridge connecting Tasmania to Australia with grasslands and scrub heath found across the area where the Bass Strait now lies.
